[JAXRS] Mathing resource method based on empty/non-empty body

[Andrei Shakirin]

Hi,

Use case: there is JAXRS service interface containing two POST methods:

                    @POST
                    @Path("{userId}/status")
                    Customer activate(@PathParam("userId") long userId, 
@QueryParam("token") String token);

                    @POST
                    @Path("{userId}/status")
                    Customer activate(@PathParam("userId") long userId, 
@QueryParam("token") String token,
                                                SyncPolicyTO policyTO);

Both methods have the same URL, the difference is just that the first one 
expects no request body and the second one expects policyTO object in the 
request body.
Question: is it basically possible for runtime to match resource method based 
on this criteria?
I didn't find explicit statement regarding it in the JAXRS spec.
Currently for CXF:

a)      In case if method has @QueryParam, I always receive either BadRequest 
error from the service by call activate()

b)      If method has no @QueryParam, the first method is always called
Looks a little bit strange for me.

Any ideas how it should work?

Regards,
Andrei.
